Question

question
identify the greatest common factor of 9wy and 6z.
answer attempt 1 out of 2

Explanation:

Step1: List prime factors of coefficients

Prime factors of $9$: $3 \times 3$
Prime factors of $6$: $2 \times 3$

Step2: Find common prime factor

The only shared prime factor is $3$.

Step3: Check variable commonality

Terms $9wy$ has variables $w,y$; $6z$ has variable $z$. No shared variables.

Step4: Combine common factors

The greatest common factor is the product of shared primes and shared variables (none here).

Answer:

$3$
